Mature Prunus ϫ yedoensis leaves (50 g) were collected in and around Chonbuk National University, Iksan, South Korea and washed thoroughly with distilled water, cut into small pieces, and boiled in 200 ml of sterile Nanopure water (conductivity ϭ 18 μ Ω /m, TOC Ͻ 3 ppb, Barnstead, Waltham, MA, USA) for 30 min to obtain the extract, followed by fi ltration (Whatman No. 42) and storage in a refrigerator for future use. One hundred milliliters of 0.1 M zinc nitrate [(Zn(NO 3 ) 2 .6H 2 O)-, Sigma-Aldrich, St. Louis, MO, USA] was added dropwise using a burette into 20 ml of the hot leaf extract under continuous stirring at 80 ° C for 8 h. Th e ZnO nanocrystals were synthesized through reduction of zinc nitrate by the phytochemical polyphenols present in the leaf extract, which are essential for the ligation of transition metal ions to form metal oxide nanocrystals (Vanathi et al 2014 , Yuvakkumar et al. 2014) . During the reaction, a yellowcolored precipitate was obtained as an initial conformation. Th e precipitate was washed several times with ethanol, followed by calcination at 450 ° C for 1 h in a furnace (AJEON Heating Industrial Co., LTD, Gyeonggi-do, South Korea). Finally, a white powder was obtained and used in subsequent experiments.

For lithium doping in IZO film, 16.8 mg of lithium nitrate (Sigma‐Aldrich, 99.99%) was added in the mixture of indium(III) nitrate hydrate and zinc nitrate hexahydrate in 1 mL of deionized water. For F‐doped IZO, 34.4 mg of indium(III) fluoride trihydrate (Sigma‐Aldrich, 99%) was mixed with 14.5 mg of zinc nitrate hexahydrate in deionized water. The solutions were mixed overnight at room temperature and coated on substrates using the same recipe for undoped IZO film described above. For hydrogen peroxide treatment, 30% H2O2 was coated on deposited IZO film and annealed at 120 °C for 5 min. UV–ozone treatment was carried out on IZO film with 365 nm UV optical source (365 nm, 22 mW m−2) for 15 min and ozone generating system (PSDP‐UVT, Novascan Co.) for 30 min.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
